To alt r1.1/1 om, 'it may concern.:

Bc it .known that I, HARRY M. PFLAenii,

a citizen oit 'the United States, residing at St. Louis, iilissonri,have invented a certain new and useful" improvement in `Car- Trucks, ofwhich the followingis a full,

A clear, and 'exact' description, such as will enable others skilled inthe art to which it vappertains to make and use the same, referencebeing had to the accompanying drawings, forming part of thisspecification, in which Figure 1 is a top plan view of a car truckconstructed in accordance with my invention, parts thereof being brokenaway for the purpose of more clearly illustrating certain details ofconstruction of said truck. Fig. 9 is a side elevation partly insection,

. said view being taken approximateiy on the line 2-2 oi' Fig. l. Fig. 3is an end elevation partly in section, said view being takenapproximately on the line 23--3 of Fig. l. Fig. et is a perspective viewshowing one end of one of the wheel pieces ofthe truck and the ends ofthe corresponding equalizer bars. Fig'. is a plan view ot a modifiedconstruction of the end portion of the wheel base.

v lliy invention relates generally vto car trucks and more particularlyto the arrangement and construction ot' the end portions o'f-tlie wheelpieces of the truck ltraine and the end portions of the equalizer bars.

incertain typos of car trucks, and pai'-,

tioularly those used beneath trailer' cars operating` on street andsuburban 'i ilways it is desirable to provide a truck having aconiparatively narrow wheel base and a coinpartively low center bearing`plate, which latter arrangement permit-s the ioor of the car body tooccupy a comparatively low plane, consequently reducing the number ofsteps at the sides of the carv platforms or at the entrance and exitopenings.

The principal objects of niy invention are, to construct a comparativelysimple, strong anddurable car truck particularly adapted for ars usedoulstreei and interurban'railways, which truck has a comparativelyshortwheel base and the `truck Jframe being arranged ina comparatively lowplane and lying wholly between the journal boxes,

and further to construct the truck frame' comprising the wheel vpiecesand transorns'.

ltop of the journal boxes.

ina-single piece, thereby obtaining ample The traine of my improvedtruck is formed in a single piece, preferably by casting, and comprisesa pair of flanged transoins 4, the same being spaced asutiicientdistance apart to accommodate a truck bolster 5 of ordinaryconstruction,and integral with the ends of these' transoins are flangedwheel pieces G, the end portions oit-.which are extended downward toform depending' .heads or brackets 7.

Pairs of equalizer bars 8 of ordinary construction are arranged betweentliejournal boxes 3, and portions of these equalizer bars` near theirends are bent so as to forni vertically disposed l'egs 9 which occupypositions against the inner side faces of the journal boxes 3, and theends 10 of said equalizer bars are bent so asl to occupy a horizontallyves disposed plane, said ends bearing directlyoii- Formed on Or fixed tothe inner lug 3, the saine occupying a posit-ion bef tween the lowerportions of the legs 9 of the face of.. .each journal boi; 3 is aninwardly projecting:

equalizer bars and being fixed thereto inv a `f suitable manner,preferably by` a bolt or rivet. j

Arranged between thev horizontally disposed ends 10 of the equalizerbars and iixled thereto inv anyv 'suitable manner is a spacingl bloc-k11, the samebearing directly-on top of vthe corresponding jouiuaLboX.

Fixed in any suitabloinanuer to .the outer faces of the dependingvheadslfoi brackets 7 of the wheel pieces are chat-lug plates 12,

ico

which, during the" vertical movement of the,

truck fraine,be`ar against the adjacent faces of the spacingiblocks 11and journal boxes 3; Formed On or Xe'd to tlie.-,undeisides`of .thewheel pieces are spring seats 13 audy nected to and depend' from thetruck framev is a spring plank 16, the central portion of which iselevated with respect to its ends in order to accommodate certain vofthe brake rods 1T. Supported by the' ends of the spring plank 16 are theordinary elliptic springs 18 which support the ends of the` truckbolster 5. The bolster 5 carries the usualV center bearing plate 19 andthe` side bearing members 20. y

In themodied construction illustrated in Fig. 5 the end of the wheelpiece 6 is bifurcated and the legs 6a thus formed extend downwardly onopposite sides of a. single' equalizer bar 8a.

It will be noted in my improved construction of car truck that the endsofthe wheel pieces terminate inside the journal boxes, and the dependingheads 7 on the ends of said wheel pieces are positioned between theupper portions of the legs 9 of the equalizer bars. sides of eachdepending head 7 and consequently the truck Jframe on which the headsare formed is etectually held against excessive horizontal movement withres ect to the equalizer bars, but the truck ame and parts carriedthereby are free to move vertically with respect to said'equalizer barsand the axles and wheels. l

My improved truck is comparatively simple in constriietion, can bereadily assembled or taken apart, provides a truck having a comparativeshort wheel base, and by reason of its compactness, is particularlyadapted for use in connection with trailer cars used on street andinterurban railways.

4It will be readily understood that minor changes in the size, form andconstruction of the various parts of my improved truck can be made andsubstituted for those herein shown and described without departing fromthe spirit of my invention, the scope of whichis set forth in theappended claims.

I claim:

1. In a car truck, the combination with equalizer bars between thejournal boxes, of a truck frame, the end portions of` which bear againstthe inner side faces of the journal boxes between the adjacent portionsof the equalizer bars.

2. In a car truck, the combination with pairs of equalizer bars arrangedbetween the journal boxes, of a truck frame cast in a single piece andcomprising transoms, and wheel pieces, the ends of which are locatedbetween the pairs of equalizin bars immediately adjacent to the inner sie wallsof` the journal boxes.

3. In a car truck provided with journal Thus bearings are formed onthree boxes, equalizer 'bars the end portions. of.

which are substantial y of invertedL-shape and engage saidl journalboxes andtruck frame, the wheel pieces of Whichflieyvholly between thejournal boxes.
